An oxygen insensitive azoreductase was purified from a novel bacterial strain (Staphylococcus sp. KU898286) that was isolated from an abandoned site of the textile waste discharge unit. The isolated enzyme had efficiently cleaved the azo-bonds through reductive transformation under aerobic conditions. Initial phenotypic characterization and final construction of phylogenetic tree on the basis o...

This study includes isolation, purification, and identification of algae from different environmental places (Tigris River and canal around AlJadriah) during February 2008. Nine unialgal cultures were obtainedwhich included 4 species of blue-green algae, 4 species of green algae, and 1 species of diatoms. However, contaminant bacteria and fungi were isolated from 4 of these algal cultures which...

A new antibiotic U-62162 has been isolated from the fermentations of Streptomyces verdensis Dietz, sp. n. (UC-8157). The compound has been characterized and its gross structure has been elucidated. The antibiotic inhibited the growth of Gram-positive bacteria (particularly Staphylococcus aureus) but was inactive in experimentally infected animals.

Two new fungal metabolites, penicipyrone (1), and penicilactone (2), were isolated from the marine-derived fungus Penicillium sp. PSU-F44 along with three known macrolides, (+)-brefeldin A (3), (+)-brefeldin C (4), and 7-oxobrefeldin A (5). Their antimicrobial activities against methicillin-resistant Staphylococcus aureus SK1 and Microsporum gypseum SH-MU-4 were examined.

A collection of fungal isolates was obtained from a complex microbial mat, which occupied an iron-rich freshwater spring that feeds into Clear Creek, Golden, Colorado, USA. Two of the fungal isolates, a Glomeromycete (possible Entrophospora sp.) and a Dothideomycete (possible Phaeosphaeria sp.), were investigated for bioactive secondary metabolites. In total, six new compounds consisting of cle...

ISSN: 2319-7706 Volume 4 Number 5 (2015) pp. 172-190 http://www.ijcmas.com Neonatal sepsis is a leading cause of neonatal mortality in developing countries. Identification of the etiological agents of neonatal sepsis is essential for effective treatment. Out of 106 microbial isolates recovered from blood cultures of late onset neonatal sepsis (LONS) patients, only 70 (66 %) isolates were Gram-p...

Cow urine has been used as medicine since ancient times andthe scriptures of Ayurveda consider cow to be the elixir life. The present study analyzes inhibitory effects fresh at different pH (8.2,4.4,3.8) intervals 5,10, 20,30 days and antibacterial activity was analyzed against Escherichia coli , Staphylococcus aureus Klebsiella sp. It found that no bacterial growth in 3.8 after 30 days. Shelf ...

In the present study, effort has been made to find the antimicrobial activity of haemolymph collected from freshwater crab, Paratelphusa hydrodromous. The haemolymph collected was tested for antimicrobial assay by disc diffusion method against clinical pathogens. Five bacterial species, namely, Escherichia coli, Klebsiella pneumonia, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aur...

Recent developments in marine drug discovery from three South African marine invertebrates, the tube worm Cephalodiscus gilchristi, the ascidian Lissoclinum sp. and the sponge Topsentia pachastrelloides, are presented. Recent reports of the bioactivity and synthesis of the anti-cancer secondary metabolites cephalostatin and mandelalides (from C. gilchristi and Lissoclinum sp., respectively) and...
